Ask me some time for the full details. One time a rather large man got a little too into character at an event. He took my brother in law as his hostage and put a gun to his head. Or at least I should say he tried. My brother in law has taken martial arts classes for a long time and he was in training to be an officer at the time. Within a moment he had the large man squealing for mercy as he disarmed him and had his arm wrenched behind his back. You never know what peoples instincts are and what they might do.
